ALL Classes Grand Overlord

As you all know AP accumulation is like XP accumulation : It's all about time and focus and not necessarily skill … so this is not a post about skill.
Over the weekend I loaded into an argument in zone between 2 people claiming to know the 1st player on PC NA to rank up 4 different classes to Grand Overlord - I had never heard of either but I did know of a player who had ranked up 5 different classes( now 6 with Necro) to Grand Overlord. After much disagreement and debate we decided to settle our argument on the forums. Here is proof of the player i know(provided i did this correctly)https://imgur.com/a/2lID1nQ

Never knew him too - he helped me and a few friends get Emperor on a dead Malacath campaign a few months back - much resource PvDoor and wall reps involved to pass others on the leaderboard but no 'boosting' - let's see your proof or are you just shaming/hating ?
